CW61100B Heavy Duty Manual Lathe: Built for Large-Scale Turning with Endurance

The CW61100B manual lathe stands out as a flagship model among heavy duty horizontal lathes. With a 1000 mm swing over bed and bed width of 755 mm, it is engineered for large workpiece processing while maintaining mechanical simplicity and robustness. According to public catalogs, it supports workpiece weights up to 6000 kg and center distances ranging from 1500 to 8000 mm.

Structural Strength & Design Philosophy
The CW61100B utilizes a box-type bed with internal and external ribbing to reinforce rigidity—derived from classic gap lathe design philosophies. Its guideways undergo medium-frequency hardening and finish grinding to preserve alignment under load.The heavy casting structure and deep cross sections help this lathe resist deflection even under high cutting forces.

Machining Capacity & Key Specifications

• Swing over bed: 1000 mm 

• Swing over cross slide: approx. 615 mm 

• Center distances: 1500 / 3000 / 5000 / 6000 / 8000 mm 

• Maximum turning length: 1350 / 2850 / 4850 / 5850 / 7850 mm 

• Spindle bore diameter: 130 mm 

• Spindle taper: 1:20 Metric No.140 

• Spindle speeds: 21 steps from 3.15 to 315 rpm 

• Main motor: 22 kW 

• Sleeve travel: 300 mm with sleeve diameter 160 mm, Morse 6 taper 

This suite of specifications positions the CW61100B as a capable lathe for heavy-duty tasks, able to process large shafts, rings, bearings, housings, and other oversized components.

Operational Flexibility & Manual Control
Unlike fully automated CNC machines, the CW61100B embraces the manual lathe tradition—operators have full tactile control over carriage, cross slide, and spindle speed selection. The mechanical gear-shift and lever-based feed systems deliver intuitive operation. For environments where simplicity, reliability, and maintenance ease are essential, the CW61100B excels.

Industry Use Cases & Value Proposition
It finds wide use in industries that still rely on robust manual machining capability: heavy machinery repair, shipyards, turbine maintenance, large mold shops, and industrial maintenance workshops. Its ability to tolerate shop-floor conditions, ease of parts access, and maintenance resilience make it a long-lasting choice for shops that need high capacity without overly complex electronics.

Conclusion
The CW61100B manual horizontal lathe remains a heavy-duty classic—combining large-scale capacity, durable design, and operational clarity. It’s ideal for manufacturers or maintenance shops that prioritize mechanical reliability, ease of service, and robust workhorse performance.
